Sunk costs should not be considered when making the decision to continue investing in an ongoing project, since these costs cannot be recovered. However, many managers continue investing in projects because of the sheer size of the amounts already invested in prior periods. They do not want to “lose the investment” by curtailing a project that is proving to not be profitable, so they continue pouring more cash into it. Rationally, they should consider earlier investments to be sunk costs, and therefore exclude them from consideration when deciding whether to continue with further investments. Rego, Arantes, and Magalhães point out that the sunk cost effect exists in committed relationships. Therefore, It should not be a factor in current decision-making.
At some point, the rent may become an expense you can’t recover through your shop’s profit (a sunk cost). But after spending so much money on repairs, you decide you’d rather fix the old costing methods and important costing terms car so that the money you spent previously wasn’t all for nothing.

After the renovation, you are assessing your costs and earnings and wondering if you can stay afloat financially. The sunk cost fallacy is a cognitive bias that makes you feel as if you should continue pouring money, time, or effort into a situation since you’ve already “sunk” so much into it already.

What is the sunk cost fallacy?
It is irrational to use irrecoverable costs to justify a present decision. If we acted rationally, only future costs and benefits would be taken into account. Regardless of what we have already invested, we will not get it back whether or not we follow through on the decision. In accounting, finance, and economics, all sunk costs are fixed costs. The defining characteristic of sunk costs is that they cannot be recovered.

A sunk cost refers to money that has already been spent and cannot be recovered. A manufacturing firm, for example, may have a number of sunk costs, such as the cost of machinery, equipment, and the lease expense on the factory. Sunk costs are excluded from a sell-or-process-further decision, which is a concept that applies to products that can be sold as they are or can be processed further. Overcoming the sunk cost dilemma involves recognizing sunk costs, reframing your perspective, evaluating the current situation, and considering opportunity cost. You must usually be deliberate when considering sunk costs and be mindful of how they may (or more importantly not) have implications on future decisions.
An example of a sunk cost would be spending $5 million on building a factory that is projected to cost $10 million. The $5 million already spent—the sunk cost—should not be taken into account when deciding whether the factory should be completed. What ought to matter instead are expectations of future costs and future returns once the factory is operational. A sunk cost is a cost that has already occurred and cannot be recovered by any means.

The sunk cost fallacy can affect our decisions in response to other people’s past investments. The sunk cost fallacy occurs because we are not always rational decision-makers. On the contrary, we are often influenced by our emotions, which tie us to our prior commitments even in the face of evidence that this is not in our best interests. Instead of considering the present and future costs and benefits, we remain fixated on our past investments and let them guide our decisions. The sunk cost fallacy occurs when we feel that we have invested too much to quit.

It pays $5,000 a month for its factory lease, and the machinery has been purchased outright for $25,000. The company produces a basic model of a glove that costs $50 and sells for $70.
Why is the sunk cost fallacy a problem?
If you resell the equipment for a lower cost than the purchase price, the difference between the original cost and the resell cost is the sunk cost.

Opportunity Cost
They recognized that the opportunity cost of abandoning the project was substantial in terms of international prestige and the cultural and economic benefits the completed Opera House would bring to Sydney.

In December, its value has dropped to $100 even though the overall market and similar stocks have risen in value over the year.
